Dermoid ovarian cyst: causes, treatment,operation, is it possible to get pregnant

Update: October 2018 Among women diagnosed
ovarian cyst in 20% of cases observed dermoid cyst. This
a cyst is not life threatening in case of
small size, but with the growth it must be removed.
Dermo cyst does not apply to hormone-active tumors,
therefore does not affect the menstrual cycle and childbearing
function. However, from 1 to 3% of cases described education
reborn into ovarian cancer.

The term “dermoid cyst”

Cysts are sacculate formations that are filled
fluid. This fluid is produced by the walls of the cystic capsule.
Ovarian cysts are functional and true. Functional
cysts may disappear on their own or after
conservative treatment, the same cysts are removed only
operative way and are considered benign tumors. If a
the contents (fluid secret) of functional cysts are formed by the walls
their capsules, the contents of true cysts arises by dividing
cell capsules. True ovarian cysts include
endometrioid, cystadenoma (serous and mucinous),
paraovarian cyst of the ovary, and, accordingly, dermoid

Description of a dermoid cyst

Other names for dermoid cysts are mature teratoma or
dermoid This type of neoplasm refers to germ cell,
there are germinal tumors and has a round or oval shape.
The walls of the cystic dermoid capsule are thin, but sufficient

As a rule, dermoids are single-chamber, but there are two and
multi-cysts. The cavity of the mature teratoma is filled with thick
mucus-like fluid in which fatty tissue can meet
(fat), hair and teeth, bones, nerve tissue and sebaceous glands).

The growth of a dermoid cyst is very slow, but influenced by some
factors it can increase and reach 15 cm in diameter. how
usually dermoid cysts are found in one of the ovaries, but
their localization is also possible.

Dermoids can be diagnosed at different age periods, from
newborn to postmenopause. More often mature teratome is found on
right ovary, due to its anatomical features.
The right ovary is much larger than the left, it is better blood supply, and
ovulation occurs more often in it (68%).

Causes and origin of dermoids

To date, reliable causes of dermoid
ovarian cysts are being studied. However, it has been established that in the development
dermoid violations of differentiation of tissues during
prenatal period. It becomes clear that the occurrence
Mature teratomas do not cause hormonal changes, they only
stimulate the growth of education. This is due to the detection
dermoid cysts of considerable size in adolescent girls,
pregnant women and menopausal women when in the body
hormonal changes take place.

Due to the disruption of embryogenesis in the ovary,
stay and survive fragments of germinal tissue, of which in
будущем и вырастет дермоидная cyst. Germ tissues are made up of
three layers:

  • the ectoderm from which skin, intestinal parts develop,
    nervous tissue and sense organs;
  • mesoderm, which gives rise to bone and cartilage tissues,
    muscles, kidneys and blood vessels;
  • endoderm – from it develop intestinal mucosa, liver and
    pancreas, as well as lungs, thyroid and salivary

Since the development of this education are layers associated with
dermis, it was called dermoid cyst.

Violation of embryogenesis occurs as a result of
the impact on the future mother of harmful factors:

  • physical radioactive radiation very high or extremely
    low temperatures;
  • chemical exposure – the use of highly toxic drugs,
    drugs, food poisoning and household poisons,
    disturbed ecology);
  • biological – various pathogenic microorganisms, congenital
    anomalies and genetic and chromosomal abnormalities.

Provoking factors

�The following factors can “spur” cyst growth:

  • hormonal surges (periods of gestation, puberty and
  • stress;
  • chronic pathology of the reproductive system;
  • operations on the pelvic organs;
  • abdominal trauma.

Clinical picture

Dermoid grows very slowly, so there is a clear clinical picture.
for small sizes it does not. how правило, маленькие
neoplasms are detected by chance during
gynecological examination or ultrasound examination of organs

appear when teratoma reaches 5 cm.

If a дермоид в диаметре достигает 10 – 15 см, появляются
characteristic signs:

  • pains in the lower abdomen;
  • unclear, migrating pain localization;
  • чувство давления,  распирания и тяжести внизу живота;
  • increased abdominal volume (with significant size, especially in
    lean women);
  • frequent urination due to tumor pressure on
  • possible burning and soreness when urinating;
  • impaired work intestines (constipations are replaced by diarrhea, which also
    due to compression of the lower intestinal regions);
  • painful intercourse (optional).

The cyst of the left ovary is formed much less frequently than the right one, which
due to the anatomical features of the sex glands. Seldom
diagnose bilateral teratomas.

Dermoid on the background of pregnancy

Dermoid ovarian cyst and pregnancy do not exclude each other.
That is, the conception and subsequent development of the fetus is quite possible on
the background of the existing education, as the dermoid does not cause
hormonal changes in the body and does not lead to infertility.
Ovarian neoplasm can quite easily survive the whole
pregnancy without showing itself. But the growth of cyst in

A large dermoid cyst is often complicated by the fact that

The complications of dermoid include:

Torsion of teratoma

As the tumor grows and thanks to its long leg,
changes its location and can twist around its own
180 axis and even 360 degrees. how правило, это происходит
after considerable physical exertion, but can happen without
visible reasons. Twisting the legs of a dermoid causes a disturbance in it
blood circulation (blood cannot flow through squeezed vessels in
swelling), which leads to a very sharp pain, forcing
the patient must assume a forced position (horizontal, with
legs and knees bent). The pain does not even stop
taking analgesics. Against the background of discontinued circulation in

Dermoid rupture

It also provokes hard physical labor. At the time of the break

the contents of the dermoid irritates the abdominal cavity and the internal
organs that manifest peritoneal symptoms (positive

temperature, dyspeptic symptoms.

Cyst suppuration

Inflammation of a dermoid cyst may trigger
pathogenic flora in the body. It can be either sharp or
chronic inflammatory processes of the reproductive system
(colpitis, cervicitis, adnexitis and others) and other foci
chronic infection (tonsillitis, caries, pyelonephritis). Infectious
agents enter the dermoid through the blood vessels, which leads to
his suppuration. The patient has signs of intoxication, which
over time only increase, symptoms of irritation appear
peritoneum and significant abdominal pain.


In the diagnosis of pathology, the following methods are used:

Gynecological examination

Bimanual abdominal palpation
(vaginal-abdominal or recto-abdominal) allows
to palpate the elastic formation of a round or oval shape,
which is located anteriorly and somewhat to the side of the uterus. With
palpation does not feel soreness, and the tumor itself is sufficient

Pelvic ultrasound

Ultrasound (preferably with transvaginal sensor)
fairly accurately reveals the presence of a dermoid cyst. With
the study establishes the size and localization of teratoma,
the thickness of the capsule (it is thickened in a dermoid), the intensity
blood supply, the presence of contents and inclusions in it,
ECHO density of cystic elements.

MRI and CT

These research methods help to clarify the nature
neoplasms (benign or malignant).

Operative intervention

The tactics of surgical treatment depends on many factors.
The operating gynecologist should consider:

  • age of the patient;
  • the size of education;
  • location of the cyst;
  • neglect of the process (with long existing and large
    formations it is possible the formation of adhesions in the pelvis, which
    complicates the operation);
  • cyst complications (torsion or suppuration, which requires
    conducting an immediate operation);
  • nature of education (benign or

The volume of surgery to remove a dermoid cyst may vary.
Perform the following types of surgery:


This type of removal operation consists in trapping
(excision) of the cyst, while trying not to violate the integrity of her
capsules, within the healthy tissues of the ovary. Performing a cystectomy
possible with small education, when it is not yet
germinated ovarian tissue and does not violate ovarian function.
Conducted by young women planning a pregnancy.

Wedge resection of the ovary

It consists in excision of not only the education itself, but also parts
gonad (cyst damaged part of the ovary). After resection
ovarian functions are fully restored, including
reproductive (in the remaining organ remains sufficiently
follicles for egg maturation). A similar operation is performed
with a volume of education in 5 – 7 cm and with twisting the legs.


It consists in the complete removal of the ovary. In some cases, the volume
operations expand to adnexectomy — removal of the fallopian tube and
половой glands. This surgery is performed
premenopausal and menopausal patients, as well as
with complications (suppuration and necrosis of the cyst, rupture of the formation).

In 90% of cases, laparoscopy of the dermoid cyst is performed. By
Emergency laparotomy is performed (anterior
abdominal wall in a straight line of the abdomen or Pfanneshtil).

In the postoperative period is carried out medication

  • antibacterial (broad spectrum drugs: cephalosporins,

  • anti-inflammatory (metronidazole, nonsteroidal
    anti-inflammatory drugs: indomethacin, nise, ibuprofen) – not
    only reduce the risk inflammations, but also relieve pain;
  • vitamins according to the phase of the menstrual cycle for
    rapid recovery of ovarian function;
  • immunomodulators (cycloferon, timogen) – patients with
    weakened immunodeficiency.

Women planning a pregnancy for the next 6 months after
operations are shown taking COC for contraception and recovery
functions of the sex glands.

Question answer

Вопрос: Мне удалили дермоидную кисту месяц назад.
When can I plan a pregnancy?

Pregnancy can be planned no earlier than six months after
surgical treatment. During this time, treat chronic
diseases, undergo additional examinations (hidden genital
infections), redefine lifestyle (avoiding harmful

Вопрос: howой прогноз после удаления dermoid?

If the operation was carried out in a timely and efficient manner, then
menstrual, sexual and childbearing functions do not suffer, that is
favorable prognosis.

Вопрос: У меня срок беременности 12 недель. On ultrasound
identified a dermoid of small size, about 3 cm. How is it
will affect pregnancy and will not require surgery?

The presence of dermoid cysts does not affect the course
of pregnancy. But the growth of education or the occurrence of
various complications. Conduct a planned operation in the period
gestation is not required, except for the significant size of the cyst,
which in the process of growth of the uterus can twist or burst.
A planned operation in this case is performed after the 16th week and
necessarily by laparoscopy. In case of
complications performed emergency surgery
независимо от срока of pregnancy.

Вопрос: howие могут быть последствия после

Possible recurrence of pathology, when in the ovary preserved
germinal tissue in its infancy. Not excluded
the occurrence of genital endometriosis, especially when performing
operations in the period of monthly or on the eve of an emergency
(retrograde blood request from the uterine cavity to the pelvis). When
double-sided dermoid can develop infertility.

Вопрос: Обязательно ли оперироваться при наличии

Yes. The exceptions are only small formations (up to 3 cm),
who do not grow and do not cause complaints. But in any case, a woman
should be regularly monitored by a gynecologist and underwent an ultrasound scan. If you
